Methods and devices for producing artificial nails are disclosed, comprising: automatically recognizing user nail information by means of a 3D scanner (S100); recognizing a selected nail decoration design of a 2D or 3D form by means of a UV 3D printer (S200); a step in which the UV 3D printer, equipped with a device capable of adjusting a Z axis, forms a decoration layer corresponding to a curved surface of a user's nail shape with the nail decoration design recognized in step S200, on the basis of the user nail information recognized in step S100 (S300); a step in which the UV 3D printer forms an adhesive layer to be attached with the decoration layer produced in step S300; and a step of completely curing the decoration layer and the adhesive layer in a short time by subjecting same to heat treatment by using a UV lamp of the UV 3D printer, thereby printing an artificial nail in which the adhesive layer is coupled to the bottom of the decoration layer.

A wearable accessory typically worn on the back, or dorsal side, of a hand intermediate the wrist and finger, or on the top, or dorsal side, of a foot intermediate the ankle and toe. The wearable accessory includes an endless elastic band sized and shaped such that when stretched from its relaxed state fits snugly around a wearer's finger and wrist or around a wearer's toe and ankle, a bail member slidably secured to the elastic band for displaying a wearable device, a fastening arrangement for securing the bail member to the elastic band, and a mounting assembly for removably mounting a wearable device, such as a gemstone, a watch, a personal alarm or other electronic devices, on the bail member.

A variable length of a jewelry assembly includes one or more display links or sections for accepting and displaying a gemstone or another focal element. Some display links are enlarged relative to other portions. Some display links are contoured to match a curve of a digit such as a ring finger when the length is wound around the digit. A length can include coaxial elements connected to each other and are moveable in relation to each other. A length of the assembly is selected such that it fits securely around a digit of a particular user when wound an integer number of times. A size and a number of each link or length-building element are selectable to fit the assembly an integer number of times around a digit.

Embodiments of the present disclosure provide a multi-membered bracelet. The palm bracelet includes three members connected by connecting chains. In some embodiments, one of the three members is configured to rest within the space between the thumb and index finger. In some embodiments, one of the connecting chains is configured to rest within the space between the thumb and index finger.
